South Carolina Non-Structural Renovation Exam: Complete 2026 Study Guide

You've built your skills on job sites — now it's time to put them on paper. The South Carolina non-structural renovation exam is the gateway to your SC renovation contractor license, and passing it means you're officially authorized to take on interior and exterior remodeling work on commercial and residential buildings without touching structural or load-bearing components. This exam is administered through PSI and regulated by the South Carolina Contractor's Licensing Board under the Department of Labor, Licensing and Regulation. This guide walks you through everything: what's on the exam, sample questions, the right books, and how to study smart.

Exam Overview: Format, Time, and Passing Score

The South Carolina remodeling contractor exam is straightforward in format, even if the content requires solid preparation:

• Questions: 60 scored questions
• Time limit: 150 minutes (2.5 hours)
• Passing score: 70% — that means 42 correct answers out of 60
• Format: Multiple-choice, open-book
• Delivered by: PSI Testing

Yes, open-book — but don't let that lull you into a false sense of security. You have 150 minutes to answer 60 questions while also managing your reference books. That works out to roughly 2.5 minutes per question. Candidates who struggle on open-book exams are usually the ones who try to read rather than find. More on that in the study tips.

Required Study Materials

This is an open-book exam, and the reference books you bring are the same ones you need to study from. Here's the official list, with purchase links:

• Carpentry and Building Construction — Your primary reference for rough framing, sheathing, and general carpentry. Heavy on diagrams, which is exactly what you want.
• Finish Carpenter's Manual — Covers door and window trim, moldings, stair trim-out, and wood flooring. Lean on this for the finish carpentry questions.
• Gypsum Construction Handbook (7th Edition) — The definitive reference for drywall. Panel types, levels of finish, fastener schedules — it's all here.
• The Complete Illustrated Guide to Furniture and Cabinet Construction — Targets the finish carpentry and millwork content, especially wood movement and case construction.
• OSHA 29 CFR 1926 — Required for the safety section. Know where Subpart M (fall protection) and Subpart Z (hazardous substances) live.
• SC Building Code 2021 — South Carolina's 2021 Building Code with state modifications is an approved reference. Keep it tabbed for moisture control and ventilation questions.

Two tools that pay for themselves on test day:

• Sharpie Highlighters — Fluorescent ink that stands out on the page, resist smearing, and come in assorted colors so you can color-code by topic. The 12-pack covers every book.
• Redi-Tag Permanent Colored Tabs — 100 permanent adhesive tabs in five colors. Tab every major section of every book before exam day. Finding answers fast is the whole game on an open-book test.

Study Tips for the SC Non-Structural Renovation Exam

Give yourself 3–6 weeks. That's enough time to work through the material systematically without burning out. Use the official exam bulletin as your roadmap — it tells you exactly what's tested.

Build speed, not just knowledge. On an open-book exam, the skill that matters most is finding answers quickly. Tab every major section. Write topic labels on your tabs. Practice locating specific code provisions under a 2-minute timer.

Set your practice bar at 80%. The real passing score is 70%, but if you aim for 70% in practice you'll pass by the skin of your teeth — or not at all. Three clean rounds at 80% or higher signals you're ready.

Every attempt is different. The real exam rotates questions within each topic area, just like our full practice exam does. Getting comfortable with varied question phrasing is just as important as knowing the content.

Use a first-pass, second-pass strategy. Answer every question you know confidently in your first pass. Flag anything that requires book-diving and come back to it. You can bookmark questions for review — same approach works on our practice platform. Don't let one hard question eat five minutes while a dozen easy ones go unanswered.

Prioritize Associated Trades, Drywall, Metal Stud Framing, Rough Carpentry, and Windows and Doors. Those five topics together account for 41 of your 60 scored questions.
